IMPROVEMENT lN HARNESS-TUG BUCKLES.

Specification forming part of Letters Patent No. 185,601, dated February 4, 1873.

To all. who-m it may concern:

Be it known that I, FRED. SEIFERT, of Knoxville, in the county of Marion and State of Iowa, have invented a new and valuable Improvement in Harness-Tug Buckles; and I do hereby decla-re that the following is a full, clear, and exact description of the construction and operation of the same, reference being had to the annexed drawing making a part of this specification, and to the letters and figures of reference marked thereon.

Figure 1 of the drawing is a section of my harness-tug buckle. Fig. 2 is a top view of same.

This invention has relation to harness-tug buckles; and it consists in the construction and novel arrangement of the sliding-wedge plate, as and for the purpose hereinafter more fully explained.

A in the drawing designates the buckleframe, having the end bars B B and side loops C, for the attachmentof the well-known harness-straps, the hame-tug being attached to the bar B. D designates the sliding wedgeplate, having a stud, d, to enter one of a set of holes 1n the trace, shown in dotted lines.

, The buckle-frame has inclined side openings,

with the inclined portions of which the edges of the buckle-sides coincide. The buckle-plate has side arms e, which pass through the inclined openings and serve as mediums whereby the required pressure of the buckle-plate against the trace is obtained when the latter is strained. rIhe buckle-plate is also provided with curved arms e at the sides, which extend over the edges of the buckle-sides and rest thereon7 as shown. Behind these arms the buckle-plate is provided with an outwardlycurved thumb-piece, f, which, being pressed upon, disengages the stud d from the tracethe arms e serving as fulcrums upon which the buckle-plate may turn.

Having fully described my invention., what I claim as new7 and desire to secure by Letters Patent, is-

In a harness-tug buckle having inclined side openings and edges, the sliding buckleplate D having the stud d, wedging-arms e, movable fnlcrnms e', and thumb-piece f, all substantially as and for the purpose specified.

In testimony that I claim the above I have hereunto subscribed my name in the presence" of two witnesses.

FRED. SEIFERT.
